Image display apparatus

Abstract

An image display apparatus includes a first image carrier along with an apparatus for inputting an image signal. An erasable image is formed on the first image carrier in accordance with the image signal input from the image signal input apparatus. A display area displays the image formed on the first image carrier. A second image carrier, which is associated with the first image carrier, contains a visible image which is photoelectrically read and converted to an image signal. The visible image carried on the second image carrier is automatically erased after the visible image is converted to an image signal.

What is claimed is: 
     
       1. An image display apparatus comprising: a first image carrier;   image signal input means;   image forming means for forming an erasable image on said first image carrier in accordance with an image signal input from said image signal input means;   a display area for displaying thereon the image formed on said first image carrier;   a second image carrier associated with said first image carrier;   means for photoelectrically reading a visible image carried on said second image carrier and converting the visible image to an image signal; and   means for automatically erasing the visible image carried on said second image carrier after the visible image is converted to an image signal.   
     
     
       2. An image display apparatus according to claim 1 wherein said second image carrier allows additional recording of new image information thereon. 
     
     
       3. An image display apparatus according to claim 2 wherein said second image carrier extends along and in parallel to a display plane of said first image carrier and is transparent. 
     
     
       4. An image display appartaus according to claim 1 wherein said image forming means includes irradiation means for irradiating a beam to said first image carrier and developing means for developing said first image carrier irradiated by said beam. 
     
     
       5. An image display apparatus comprising: a first image carrier;   image signal input means;   image forming means for forming an erasable image on said first image carrier in accordance with an image signal input from said image signal input means;   a display area for displaying thereon the image formed on said first image carrier;   a second image carrier associated with said first image carrier;   means for photoelectrically reading a visible images carried on said first image carrier and said second image carrier converting the visible images to one image signal; and   means for erasing the visible image carried on said second image carrier.   
     
     
       6. An image display apparatus according to claim 5 wherein said second image carrier allows additional recording of new image information thereon. 
     
     
       7. An image display apparatus according to claim 5 wherein said second image carrier extends along and in parallel to a display plane of said first image carrier and is transparent. 
     
     
       8. An image display apparatus according to claim 5 wherein said image forming means includes irradiation means for irradiating a beam to said first image carrier and developing means for developing said first image carrier irradiated by said beam. 
     
     
       9. An image display apparatus according to claim 5 further comprising control means for controlling start timings of drive of said first image carrier and said second image carrier. 
     
     
       10. An apparatus according to claim 5, wherein said erasing means automatically erases the visible image carried on said second image carrier after the visible image is read. 
     
     
       11. An apparatus according to claim 5 wherein said reading means reads the visible image carried on said first image carrier and the visible image carried on said second image carrier at the same time. 
     
     
       12. An image display apparatus comprising: a first image carrier;   image signal input means;   image forming means for forming an erasable image on said first image carrier in accordance with an image signal input from said image signal input means;   a display area for displaying thereon the image formed on said first image carrier;   a second image carrier associated with said first image carrier;   means for selecting at least one of the visible image carried on said first image carrier and the visible image carried on said second image carrier to be read; and   means for photoelectrically reading the selected visual images carried on at least one of said first image carrier and said second image carrier and converting the visual images to image signals.   
     
     
       13. An image display apparatus according to claim 12 wherein further comprising means for designating the carrier to be read by said reading/converting means. 
     
     
       14. An image display apparatus according to claim 12 wherein said second image carrier extends along and in parallel to a display plane of said first image carrier and is transparent. 
     
     
       15. An image display apparatus according to claim 12 wherein said image forming means includes irradiation means for irradiating a beam to said first image carrier and developing means for developing said first image carrier irradiated by said beam.
